I encountered many problems in my study and work, and it took a lot of time to find solutions.
Now I simply open a blog to list the problems and reliable methods. First, it is convenient for me to refer to it when I encounter it again. Second, I also hope to give some help to the students who also encounter the same problem. Thanks to these bloggers for sharing.
